GAS-BURNER.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed May 9, 1907. Serial No. 372,751.

To all whom it may concern:

Be it known that I, THOMAS LEOPOLD l/VILLsoN, of the city of Ottawa, in the county of Carleton, Province of Ontario, Canada, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

In the art of gas burners, and particularly of acetylene gas burners, it has been the practice when burners producing flat flames are used, to arrange the burners so that the flames produced would form the sides of a polyhedron, the number of sides of which would correspond with the size of the burner. This arrangement has disadvantages, in that, between each of these sides a dark line produced by discontinuity of the light appears, and further as the size is increased, the burners must be moved further away from the common center. In cases where the burners are used within large lenses, as in gas buoys or light houses, this would materially reduce the intensity of the light, as to secure the maximum effect, the flames should be as near the focal center of the lens as possible. These disadvantages are overcome, in my invention, in which the burners are disposed at the apices of a polygon, the length of whose sides is less than the width of the flat flame produced, whereby the flames will overlap each other and produce a continuous band of light.

By this means, I am enabled to produce a concentrated and continuous flame, which will be similar in its light producing power to a short Argand flame, which it has been hitherto impossible to produce in a gas burner of this type. A further difliculty has been experienced in this class of burners in setting them at the correct angle in the base, and I overcome this by stamping on the base score grooves indicating the directions at which the burners are to be set.

All embodiment of the invention, is illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of the burner. Fig. 2 is a top view of the same having the osition of the flames also indicated. Fig. 3 1s a top view of the base with the burner proper removed. Fig. 4 is a sectional view along the line 22, Fig. 3, with the igniting device removed. Fig. 5 is a diagrammatic view illustrating the position of the burners. Fig. 6 is a diagrammatic view indicating the position of-the flames of the ordinary four burner light, which is usually employed.

Fig. 7 is a similar view to Fig. 6, showing the position of the flames for the ordinary siX burner light.

In the drawings like letters of reference indicate corresponding parts in each figure.

a is the base of any suitable type, which, in the embodiment illustrated, has integral therewith, three tubular projections b, c and d, within which three burners e, f and g are secured. that illustrated being the ordinary burner for acetylene gas. The tubular projections are arranged at the apices of an equilateral triangle, whose sides are substantially shorter than the width of the flame adapted to be produced by the burner. From this, it results that the flames h, i and j, when produced, extend beyond or overlap each other, thus rendering it impossible to see any clear space between them, and insuring that no matter what direction they are observed from a continuous band of light will be presented.

While the sizes of the light might be increased by adding additional burners, yet,

owing to the necessity of keeping the flame as close to the focal center of the lens as possible, I find it desirable to increase the size of the light by increasing the size of the individual burners.

To enable the burners to be adjusted when away from the factory to the exact angle required, I stamp a plurality of score grooves 7c, Z and m on the base of the burner, and the burners may then be very easily adjusted parallel to these.

The distinction between the arrangement of my burners and that hitherto employed, might very readily be seen by reference to Figs. 5, 6 and 7. In the form shown in Fig. 6 an observer looking along either of the directions 3-3 or 44 would observe a dark space owing to the incontinuity of the light in these directions. Similarly in the form shown in Fig. 7, an observer along any of the lines 55, 6-6 or 77, would observe similar dark spaces. An observer, however, looking at my improved burner, as illustrated in Fig. 5, along the direction 8-8 between the two flames and h would see the flame i, and no dark space would be visible. Further, as before pointed out, the light would be very much more concentrated towards the center.

While the invention has been described herein, with great particularity of detail, it

These burners may .be of any type,

will be readily understood that in carrying out the construction of the same, changes may be made therein, within the scope of the a pended claims, without departing from t e s irit of my invention.

' at I claim as my invention is 1. The combination with a lurality of burners adapted to produce 5 arranged adjacent to each other and at such an angle that the same correspondin edge of the flame of each burner, extends close to the flat side of the next adjacent burner at some distance from the rear edge thereof, whereby the flames successively overlap, as and for the purpose specified.

2. An acetylene gas burner comprising a at flames,

base member, a plurality of burner tips supported thereon and constituting the apices of an equilateral polygon, sides of said olygon being shorter than the width of the ames produced by the burner tips, the base member being provided with score lines thereon for positioning the burner tips whereby the flames produced will successively overla each other and prevent the appearance of dark lines between.

Signed at Ottawa, in the Province of Ontario, this first day of May, 1907.
